You shoudn't have to dig any bungs out or destroy anything in order to remove the doors.
To remove the plexi doors, lift them straight up into the top track, they should then just move vertically enough clear to the lip of the bottom track so that the panel can be tilted out at the bottom. If you still don't have enough clearence you can push the top shelf up a bit to gain additional space.
I hope that was what you asked in your original post.
